Web services and websites should block all Utah IP addresses and redirect to page explaining that because they cannot tell who’s using a VPN, their only option is to block all of Utah.

But VPN users using a VPN outside of Utah will still get through.

What Utah (and likely other dumb states soon) are trying to do is to force age verification worldwide through a state law, forcing websites to verify the age of every user from anywhere, because any user who accesses the site from anywhere in the world might possibly be someone in Utah using a VPN.
